Abstract

An electrical distribution member includes a plurality of electrical conducting wires made of a solid wire. The electrical conducting wires each include an electrical conducting body, and a coating layer provided over a surface of that electrical conducting body, while removed therefrom over a respective predetermined length including a joining portion. The electrical conducting wires include at least one first electrical conducting wire having a joining portion extending in an axial direction of a stator core, and at least one second electrical conducting wire having a joining portion bent in relation to a radial direction of the stator core in such a manner as to follow a circumferential direction of the stator core. The predetermined length of the second electrical conducting wire with the coating layer removed therefrom is longer than the predetermined length of the first electrical conducting wire with the coating layer removed therefrom.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. An electrical distribution member, comprising:
 a plurality of electrical conducting wires each being made of a solid wire, to connect a plurality of coil ends, which are protruding in an axial direction from a stator core of a rotating electrical machine, and electrodes, respectively, of a terminal block together, the plurality of electrical conducting wires each including an electrical conducting body, which is made of an electrically conductive metal, and a coating layer, which is being provided over a surface of that electrical conducting body, while being removed therefrom over a range of a predetermined length including a joining portion to be welded to the coil end, wherein the plurality of electrical conducting wires include at least one first electrical conducting wire, which has the joining portion extending in the axial direction of the stator core, and at least one second electrical conducting wire, which has the joining portion being bent in relation to a radial direction of the stator core in such a manner as to follow a circumferential direction of the stator core, wherein the predetermined length of the at least one second electrical conducting wire with the coating layer being removed therefrom is longer than the predetermined length of the at least one first electrical conducting wire with the coating layer being removed therefrom. 
 
     
     
       2. The electrical distribution member according to  claim 1 , wherein, for each of the at least one second electrical conducting wires, the joining portion is joined to the coil end in an inner side in the radial direction of the stator core relative to the joining portion of each of the at least one first electrical conducting wires, wherein the second electrical conducting wire includes a radial direction extension portion extending in the radial direction of the stator core, wherein the joining portion is bent at an end portion of the radial direction extension portion in the inner side in the radial direction of the stator core, wherein an angle formed by an opposite surface of the joining portion to the coil end and the radial direction extension portion is an obtuse angle. 
     
     
       3. The electrical distribution member according to  claim 1 , wherein, for each of the at least one second electrical conducting wires, when the joining portion is welded to the coil end, an opposite surface of the joining portion to the coil end is brought contiguous obliquely to a side surface of the coil end.
